floci-io/floci 1.5.18 on GitHub

🎉 Highlights

This release adds two brand-new services — CloudFront and AWS Config — completes Neptune with a real Gremlin Docker backend, and lights up real SNS HTTP/HTTPS endpoint delivery. SQS, Lambda, and API Gateway v2 all see substantial conformance work, including FIFO dedup scoping, a proper Lambda port-allocator pool, and ALB-routed HTTP APIs. Welcome to the 9 first-time contributors — the largest cohort yet.

☁️ New: CloudFront

Floci now emulates AWS CloudFront — distributions, origins, behaviors, and the management API. Edge-caching workflows and IaC that provisions CDN infrastructure can now be exercised locally.

📋 New: AWS Config

The AWS Config service is now supported, enabling local testing of configuration recording, compliance rules, and resource tracking workflows.

🕸️ Neptune is now real

The Neptune service introduced in 1.5.17 graduates from control-plane scaffolding to a working graph engine: a Gremlin Docker backend, full control plane, and SDK plumbing. Graph workloads run end-to-end.

📡 SNS HTTP/HTTPS endpoint delivery

http:// and https:// subscriptions are now delivered for real — subscription confirmation handshakes, message POSTs, and signature headers all work. This closes a long-standing gap for webhook-style fan-out testing.

🚦 Lambda port allocator: checkout/release pool

The Lambda runtime port allocator is now a proper checkout/release pool rather than a counter, with an actionable error message when the concurrency pool is exhausted. Expect fewer mystery "address already in use" failures under concurrent invocations.
